Janelle Riggs · Answer 1

If you mean 4 moles per litre then:

In 1 litre there is 4 moles, therefore in. 25 litres there is 1 mole.

1 mole of Magnesium Chloride would produce 2 moles of chloride ions (MgCl2 can also be written as Mg1Cl2, which dissolves to produce 1Mg (2+) and 2Cl (1-) ions: a 1:2 ratio)

So the answer is 2 moles of Chloride ions.
